WATER HEATER.

Application fled July 17, 1925. Serial No. 44,264.

- with a soap containing tank having a valved discharge pipe in communication with the hot water discharge pipe leading from the heater, whereby a .predetermined uantity of soap may be embodied in the disc arging water to mix therewith to obtain a highly eflicient cleansing fluid to be used for the purpose specified.

One of the important objects of the present invention is to provide a water heater that includes the header construction, which -comprises a vertical water column having horizontally disposed tubes arranged at the upper and lower ends thereof, a water supply pipe being associated with the upper tube while the discharge pipe extends from the lower tube; a series of coil pipes being arranged concentrically around the column and communicating with the upper and lower tubes whereby to effect a circuitous flow of water from the upper to the lower tube.

Other features, details, and advantages derived from that particular construction and association, will becomeapparent from the detailed description and the appended claims.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same:

' Figure 1 is a side elevation. with portions broken away to show the construction of the water heater more plainly.

Figure 2 is a horizontal section through the water heater showing the arrangement of the circulation unit more plainly.

Figure 3 is a side view in section and elevation of a header embodied in the water heater.

Figure 4 is an end elevation of the header. Figure 5 is a detail view of the lower portion of the soap container.

Attention is first directed to the water heater which is generally designated by the reference character 1. This comprises a vertically elongated casing 2, at the bottom of which is a suitable burner 3. Supported above the burner is a header 4 of the construction more plainly shown in Figures 3 and 4. Referring to these figures it will be seen that the header comprises a vertical column 5, at the top of which is a horizontal tube 6. .The tube 6 is divided into a primary and secondary compartment, by reason of the partition 7 which is arranged intermediate the ends of the tube. The secondary compartment is divided into separate chambers by reason of the vertical partition 7 The innermost chamber is provided with an outlet opening 8, while the outermost one of the chambers is provided with the inlet and outlet openings ,9 and 10, respectively. 1

' The tube 6 is provided with an opening 11 which communicates with the vertical column 5 as well as with the innermost one of the chambers formed in the secondary compartment. A depending water conducting pipe 12 extends downwardly in the water column 5 and the upper end of this pipe communicates with the primary compartment of the horizontal tube 6 in the manner as clearly shown in Figure A removable cap 13 is arranged on the outer end of the secondary compartment, while a valved supply pipe 14. is connected to the opposite end of the tube. This pipe has communication with a suitable source of supply of cold water, not shown.

At the bottom of the vertical volumn 5 there is arranged a similar horizontal tube 15. Onepside of the vertical column 5 extends into this tube as shown at 5 for dividing the lower horizontal tube into primary and secondary compartments, A cap 16 is provided for the outer end of the primary compartment and this primary compartment is in communication with the vertical column. The secondary compartment formed by the partition or extension 5' is divided into inner and outer chambers by reason of the partition 17. The innermost chamber is formed with the inlet and outlet openings 8 and 9, respectively, while the outermost chamber is provided ..with an inlet opening 10. A discharge pipe 18 has communication with the outer open end of the outer chamber of said secondary compartment of the lower horizontal tube 15.

' centric coils, the inner one of whic is designated by the reference character 19, the outer one by the character 20, and the intermediate one by the character 21. The ends of the inner coil are connected with the holes 8 and 8; the ends of the intermediate coil with the holes 9 and 9"; while the ends of the outer coil are connected-with the holes 10 and 10*. This provides an unusually tortuous circulation of the fluid to insure that it shall be heated intensely before entering through the discharge pipe. At this time it will be noted that a small drain pipe 22 leads from the connection of the lower end of the intermediate coil 21.

,Appropriately supported on one side of the upper portion of the water heater 1s a tank 23 for a cleansing fluid, such as a li uid soap, or its equivalent. This tank is providedwith a suitable filler 24, and is provided at its bettom with a valved discharge pipe 25 which connects with the valved portion 26 of the aforesaid discharge pipe leading from the water heater. Then there is a flexible hose 27 which, in practice, is provided on its outlet end with an appropriate nozzle, swab or the like. Extending upwardly from the pipe 26 is the vertical hot water or steam supply pipe28, the upper end of this pipe extending into the top of the container 23. The pipe 28 cooperates with the pipe 18 in supplying hot water or steam to the tank or container 23. A steam gage 29 of any well known construction is adapted to be associated with the tank 23 and also cooperating therewith is the safety valve 30 of any appropriate construction designed with a view to blow off when excessive steam is generated as a precautionary measure.

It is obvious that the flames from the burner at the bottom of the casing will iminge upon the set of coils. These coils will e filled with -'water entering through the supply pipe 14, passing downwardly through the depending pipe 12 in the header, and then upwardly through the column 5, and then on through the coils according to their connection with the header tubes. As the hot water or steam, as the case may he, passes out through the discharge pipe, a quantity of soap will be mixed therewith, thus providing an eflicient cleansing fluid which can be sprayed or otherwise projected onto the surface of the car to be washed.

description in connection with the drawings will enable personsskilled in the art to which the invention relates to obtain a clear understanding of the same. Consequently, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired. 2

' Having thus described the invention, what I claim as new is 1. A water heater comprising a easing, a header arranged therein, the same comprising a vertical column, tubes arranged horizontally at the upper and lower ends of the column, a water supply pipe communicating with one end of the upper horizontal tube, a discharge pipe extending from one. end of the lower horizontal tube, a series of pipes extending between the upper and lower horizontal tubes and communicating therewith, said tubes and the vertical column being so constructed as to cause the water to flow from the upper tube to the lower tube in a circuitous manner through said pipes before being delivered to the discharge pipe, and a burner arranged in the casing below the header.

2. A water heater of the class described, comprising a casing, a header arranged therein, the same comprising a hollow vertical column, a tube arranged horizontally upon the upper end of the column, an additional tube arranged horizontally across the lower end of the column, the portion of the upper tube which extends across the top of the vertical column having a pair of spaced openings formed therein for communicationings for dividing the tube into primary and secondary compartments, a vertical partition for dividing the secondary compartment into inner and outer chambers, a water supply pipe communicating with the primary compartment, the innermost chamber of the secondary compartment being provided with an outlet opening, a water delivery pipe arranged vertically within the hollow column, the upper end thereof extending into the opening formed in the primary compartment in the upper tube, the secondary compartment having inlet and outlet openingsi respectively formed in the outermost chamber thereof, a vertical partition within the lower horizontal tube and forming a continuation of one side of the vertical column for dividing the lower tube into primary and secondary compartments, a partition in the. secondary compartment for dividing the same into inner and outer chambers, a water No doubt, a careful consideration of the discharge pipe-extending from the outer end of the outer chamber, the primary compart ment alone communicating with the vertical] series of coil pipes arranged concentrically around the Water column, the upper ends of the coil pipes communicating with the respective openings formed in the inner and outer chambers of the secondary compartment, the lower ends of the coil pipes communicating With the respective openings formed in the inner and outer chambers of 7 the lower secondary compartment whereby the water will flow through the header in a 1 circuitous manner, and a heater arranged in the casing below the header. 1
